Searching for kinematic signs of ram pressure stripping in z=1.6 clusters with resolved ALMA CO(2-1)
Description
The evolution of the inter cluster medium over cosmic time, and its interaction with galaxies within those clusters, is key to
understanding galaxy evolution and quenching processes. We present spatially resolved ALMA observations of 24 galaxies across
three clusters at z=1.6, the largest such sample of cluster galaxies observed at this redshift. We find signs of interaction with the ICM,
through the influence of ram pressure stripping, to be affecting the molecular gas in these galaxies. We find signs of enhanced
molecular gas fractions, kinematic disturbances in the disk, and asymmetric head-tail morphologies, consistent with observations of
ram pressure stripped galaxies at low redshift. We present preliminary results of our spatial and kinematic analysis of these galaxies,
and compare the properties of galaxies in these clusters to low-redshift clusters in which the effects of ram pressure have been
observed.
